Plasma Physics Exam 2024 1.5 Plasma Frequency The plasma frequency, 2 = ne2 , (1.5) ωp ǫ0 m is the most fundamental time-scale in plasma physics. Clearly, there is a different plasma frequency for each species. However, the relatively fast electron frequency is, by far, the most important, and references to “the plasma frequency” in text-books invariably mean the electron plasma frequency. It is easily seen that ωp corresponds to the typical electrostatic oscillation frequency of a...

A) that the price and quantity sold are determined in a single market B) that the prices and quantities sold are simultaneously determined in all markets C) the way the whole economy achieves equilibrium D) that international markets affect domestic markets, which in turn affect local markets 2. A key assumption of the supply and demand model is that: A) each firm's good is unique and cannot be duplic...

1. We can choose δx = 0, δy = δ. The equation of the ellipse x = cosθ cosωt y = sinθ cos(ωt − δ) reads in Cartesian coordinates The direction of the axes is obtained by looking for the eigenvectors of the matrix which make angles α and α + π/2 with the x-axis, where α is given by tanα = cosδ tan2θ The vector product of the position ~r with the velocity ~v, ~r ×~v, is easily seen to be so that the sense of rotation is given by the sign of the product sin2θsinδ...
